It’s the time of year when holiday parties are prevalent. Whether you like your job and your co-workers or not (that’s another story), it’s almost an un-written obligation to attend your company’s holiday party. So what will you wear to ensure that you’re not over-doing it but still stylish enough to demonstrate your personal style outside of those four walls you call work?

While no one ever really says what you can or cannot wear to a holiday party, there are a few dos and don’ts to consider. Although it’s not actually at your office, it’s still a work function equipped with all of your co-workers, your boss, and possibly your boss’ boss. So with that in mind, the underlying rule is to keep it professional.
